[Systemic embolism and thrombosis of the left atrium in a patient in sinus rhythm with cardiac amyloidosis].

The authors report the case of a female patient admitted for complete heart failure with a diagnosis of type AL amyloidosis associated with dysglobulinaemia. While in hospital, she developed femoral embolism found to be secondary to atrial thrombosis in the absence of any supraventricular arrhythmia. The frequency and mechanism of intracardiac thrombosis and embolic accidents in cardiac amyloidosis are discussed in the light of this case.
